Vectors

[mary9734]

Value will be stored in a vector but answer should stop at repeating number.
ex 988 / 56
Answer 17.6428571429

But I want Answer to be 17.642857

First get the integer quotient (17 in this example) and the remainder (36). Then start a loop:

//digit 1:
r = 360, r/d = 6, r%d = 24
//digit 2:
r = 240, r/d = 4, r%d = 16
//digit 3:
r = 160, r/d = 2, r%d = 48
//digit 4:
r = 480, r/d = 8, r%d = 32
//digit 5:
r = 320, r/d = 5, r%d = 40
//digit 6:
r = 400, r/d = 7, r%d = 8
//digit 7:
r = 80, r/d = 1, r%d = 24
//digit 8:
r = 240, r/d = 4, r%d = 16

At this point r for digit 8 is equal to r for digit 2, so you know that this is where the repeating decimal starts. So the number up to the first repeating decimal is
17.6428571
